Most plants out there are hybrids really, where the breeders are trying for the best of both yeilds and high. Depends on what type of high you like. Clear and uplifting(sativa), or cloudy stuck on the couch type high(indica). Indicas give higher yeilds since they were initially produced for their resin and hash making. Seems to me that a lot more of the older mosre experienced smokers and conissours really prefer the sativa high. A lot of younger people like the indica or they don't really know the difference as long as they get stoned
